Here is my table for Splenda tablets.
1 tablet = 0.075g carbs = 1 tsp regular sugar (1tsp granulated Splenda)
4 tablets = 0.3g carbs = 1 tbs regular sugar (1tbs granulated Splenda)
12 tablets = 0.9g carbs = 1/4 cup regular sugar (1/4 cup granulated Splenda)
24 tablets = 1.8g carbs = 1/2 cup regular sugar (1/2 cup granulated Splenda)
48 tablets = 3.6g carbs = 1 cup regular sugar (1 cup granular Splenda)
Hope this helps.
Also, it is the filler they use in the granulated splenda that contains all the carbs. The tablets do not have this so are therefore lower.
I purchased a mortar and pestle and a pastry brush for crushing my Splenda tablets. Previously I was using a large meat mallet to crush the tablets. The mortar and pestle and brush work so much better and I use them every day.
Now if only I could purchase Splenda tablets in bulk - they are not cheap and also it is fiddly getting the tabs out of the packet - especially when a recipe calls for 48 tablets.
